build-ibmcloud-win2012r2-x64-2 fails builds because it cannot delete jenkins/tmp folder

[adamfarley]

Action requested:
Please can someone with access to build-ibmcloud-win2012r2-x64-2 take a look at E:\jenkins\tmp and see if they can tell why we can't delete it?

Note:
Please avoid deleting the folder yourself, or restarting the machine. We'd like to figure why this issue has occurred so we can prevent it happening in the future.

Error message:

20:27:33  ERROR: Failed to clean the workspace

Sorry, I removed the file manually before I saw this issue (@sxa asked me to check the machine, via Slack)
We have a fix for this in other Windows machines : adoptium/temurin-build#1956
So, I'm adding E:/jenkins/tmp etc to that list here: adoptium/temurin-build#2204

Closing issue, but I'm going to raise another one in openjdk-build to aim to get a less hacky solution: adoptium/temurin-build#2205
